What is the size of a female down jacket with a height of 1.6m and a weight of 100 kg?

Under normal circumstances, it is L size, but now the specifications of down jackets have changed, because there are many types of down jackets on the market, including thin ones, bottoming ones and artificial ones. The specifications are all different, depending on whether you need to add clothes inside when you actually wear them. If not, size m will do, and the shoulder width is not big. For example, people in the northeast have wider shoulders, so they must be size L, but people in Guangdong don't want it. If you buy it online, be sure to tell the shopkeeper your shoulder width, sleeve length, garment length and bust, and they will give you advice, otherwise you can't judge a more suitable size just by your height and weight.
